VO2 max refers to the maximal rate at which your muscles metabolically use oxygen from your blood to generate energy. VO2 max is measured in milliliters per kilogram per minute (mL/kg/min). This value reflects overall cardiorespiratory fitness and can be a metric for tracking progress and fitness. In addition, when looking at VO2 max in relation to all-cause mortality, there is a clear trend that a higher VO2 max correlates with a reduction in all-cause mortality.

 

Below is a chart to see where you stand. VO2 max will decline with age but can still be improved with proper training. It is never too late to tailor your training to improve your cardiorespiratory fitness.

 

A few ways to improve your VO2 max is to start by increasing your base, or zone 2 training. Once a solid base is developed, incorporating higher intensity workouts, in addition to zone 2 training, is needed to really boost your VO2 max.

 

**Remember, never start a new training regimen without first consulting your healthcare provider.
